Sonography, also known as ultrasound imaging, is a medical imaging technique that uses high-frequency sound waves to produce images of the inside of the body. Sonographers, also known as ultrasound technicians, use a handheld device called a transducer to send sound waves into the body and then receive the echoes to produce images.

Sonography is commonly used for prenatal care, to monitor fetal development and detect any potential problems. It is also used to diagnose and monitor a variety of medical conditions, such as gallstones, liver disease, and cancers.

Some common types of sonography include:

• Obstetric sonography: Obstetric sonography is used during pregnancy to monitor fetal development, detect any abnormalities, and guide certain medical procedures.
• Abdominal sonography: Abdominal sonography is used to examine the organs in the abdomen, such as the liver, gallbladder, and pancreas, to diagnose and monitor conditions such as tumors, cysts, and inflammation.
• Cardiac sonography: Cardiac sonography is used to examine the heart and its blood vessels to diagnose and monitor conditions such as heart disease and heart defects.
• Musculoskeletal sonography: Musculoskeletal sonography is used to examine the muscles, tendons, and joints to diagnose and monitor conditions such as sprains, strains, and arthritis.

Overall, sonography is a safe and non-invasive medical imaging technique that provides valuable diagnostic information for a variety of medical conditions. Sonographers play a critical role in performing sonography exams and providing accurate images for healthcare professionals to diagnose and treat their patients.
